E421, also known as mannitol, is a food additive that is actively used in the food industry as a sweetener, as well as to give products texture and volume.
Mannitol, despite being a carbohydrate, differs from sugar in that it has little impact on blood glucose levels, making it popular in the keto diet.
Mannitol has a low glycemic index. However, it is worth noting that consumption of mannitol in large quantities can cause stomach upset and have a laxative effect.
Mannitol is often used in the production of dietary products, chewing gum, lozenges, medicinal preparations, toothpaste, and other goods.
